If you are starting from scratch and don't know your way around the 
linux system, why not use one of the 'appliance' style distributions 
like ClearOS (fairly new) or SMEserver (older but still works)?  These 
are based on CentOS code but have a simple web interface for 
configuration and will probably set up the firewalling/NAT better than 
you would do by yourself.

But to answer your question - the only difference between the caching 
nameserver package and a normal nameserver is that the caching version 
will overwrite your local configs on updates (since you shouldn't have 
made any changes).  If you want to have a local zone for your own 
machines - even if it isn't official or public, you don't want the 
caching version.
